Mount and Musket Battalion is a multi-player total conversion that tries to accurately represent the time period around the end of the Napoleonic Wars (1812-1815).
It has historical factions with accurate units and equipment, including different types of infantry, cavalry and even usable artillery.

Brief gameplay video of the mod, that version is a rendered copy of the original, which had a broken intro, I would suggest watching the into on that link, then watching the original video for the gameplay part.

But yeah, it shows some of the different map types we can make, some basic fighting, a cannon shot, a spontaneous line battle in which we just manhandled a server and they were surprisingly compliant!

Seriously you need to download this mod and try it out, when you do you will realise how much we have put into it, how amazing the community is, and how big it is.
